Study: Eye drops (1988) without preservatives



Eye drops used without preservatives have been shown to enhance corneal healing and improve dry eye problems. Laflamme, M.Y., and Swieca, R. A comparative study of two preservative-free tear substitutes in the management of severe dry eye. Canadian Journal of Ophthalmology 23 (1988): 174-76.

Editor’s Notes: Preservatives in many products can aggravate dry eye symptoms, and even kill corneal cells. Eye drops that promise to “get the red out” will reduce circulation in the eye, decrease production of the tear film, and worse, eventually make your eyes even drier.

The most popular products featuring eye drops without preservatives are the homeopathic eye drops for women and the homeopathic eye drops for men -- both as effective aides for Dry Eyes.
